DESCRIPTION:Jianlin Xia\, Professor\n\nDepartment of Mathematics\n\nPurdue
University\n\nAbstract: In this talk\, we will present fast and superfast m
ethods for solving some important dense and sparse eigenvalue problems. We
take advantage of various types of structures in divide-and-conquer strateg
ies\, contour-integral methods\, bisection\, etc. Accelerations of the eige
nvalue solutions are made via randomization\, fast multipole strategies\, m
ulti-shifted factorization\, fast eigenvalue count\, etc. For certain cases
\, nearly linear complexity can be achieved for the entire eigenvalue decom
position. The accuracy and stability behaviors will be justified. The fast
eigenvalue solutions provide ways to tackle some major computational challe
nges in traditional numerical computations\, especially PDE solutions.
